Best ResponseYou've already chosen the best response.0well, i took each grid as "1" unit m=(y2y1)/(x2x1) it is a st line so, should be same

Best ResponseYou've already chosen the best response.0oh.. i took the yintercept as "3" instead of "4".. got ya so, it is "3/4"

Best ResponseYou've already chosen the best response.2@phi what does it mean to solve for y in terms of x? And how do I figure out the slope of a line with some like y=(3/4)x2?

Best ResponseYou've already chosen the best response.1two questions if you are given y = mx +b form (in other words you see y = number times x plus another number the number in front of the x (the coefficient of the x term) is the slope (that is why people put the equation in this form, so they can "read off" the slope

Best ResponseYou've already chosen the best response.1solve for y in terms of x that means do algebra so y is on the left side of the = and everything else is on the right side for example if you had 3x+4y= 8 that is the equation of a line. But it is not obvious what its slope is. if we solve for y, we would do this: add 3x to both sides 3x3x + 4y= 3x 8 or 4y= 3x8 (that step "moved" 3x to the right side) now divide both sides by 4 (both sides, all terms) 4y/4 = 3x/4 8/4 y= (3/4)x 2 we have solved for y in terms of x

Best ResponseYou've already chosen the best response.2So for something like 6x+3y=81 it would be 6x+3y=81 6x 6x 3y/3 =  6x/3  81/3 y =  6x/3  81/3 y = 2x  27?

Best ResponseYou've already chosen the best response.26x+3y=81 6x 6x 3y/3 =  6x/3 + 81/3 y =  6x/3 + 81/3 y = 2x + 27? That should be correct

Best ResponseYou've already chosen the best response.1yes, perfect. slope is 2 and yintercept is 27
